Vista Duplicate Folders

My administrator name is RAY and directly under the DESKTOP folder there is
a folder identified RAY that containes numerous folders (10,201 W/1.3GB)
Further down under C:\USERS\PUBLIC is another folder named RAY that has
duplicate copies of all the above referenced files in addition to a folder
titled APP DATA that contains an additional 8,075 folders w/202MB. Any
change to a folder in either of the RAY folders makes a mirror image change
to the other folder. Why are there duplicate folders? And can I get rid of
one? I tried deleating the top level folder and when I rebooted it came
back. Is this duplicaton normal???
